Mango is one of the most important tropical fruits also known as the king of fruits. In this study, the relations among 19 morphological traits of leaves and fruits corresponding to 27 mango genotypes were evaluated. Based on the results of variance analysis, there was a significant difference between genotypes in most traits. Therefore, these genotypes had diversity in studied traits. According to the results, the Sindri and Nargil genotypes had the highest and lowest number of fruits per tree (with an average of 847 and 340 pcs, respecively). Moreover, Sindri and Shahani 2 genotypes showed the highest yield per tree (with an average of 261 and 240,Kg respecively). Based on the results of the correlation coefficient, these traits showed high and significant correlation. The highest and most significant correlation (0.75) was observed between the number of fruits and yield. According to the results of cluster analysis, these genotypes could be divided into four major groups. This investigation indicates there is a high variation among mango samples which can be attributed to the sexual reproduction by seeds, its cross pollination as well as climatic variation in Iran. Since Sindri and Shahani 2 imported cultivars had the highest number of fruits, weight of fruit and yield, the Shahani 2 genotype could be suggested as an appropriate genotype in future studies, breeding programs and mango cultivation in these areas.
